\page cut_mesh_by_plane_page Cut a tetrahedron mesh by a plane
\n MeshCut works only with MED files and produces MED files, and is a standalone program.
It can be used either directly from a command shell outside SALOME, or with a GUI interface in SMESH,
provided in a python plugin that needs to be installed in your SALOME application.
\n MeshCut allows to cut a mesh constituted of linear tetrahedrons by a plane.
\n The tetrahedrons intersected by the plane are cut and replaced by elements of various types,
(tetrahedron, pyramid, pentahedron).
\anchor meshcut_standalone
Using MeshCut as a standalone program, outside SALOME
\n MeshCut is a standalone program, reading and producing med files.
\n
\n Syntax:
\code
MeshCut input.med output.med resuMeshName aboveGroup belowGroup nx ny nz px py pz T
\endcode
\n
\n where:
\n input.med = name of the original mesh file in med format
\n output.med = name of the result mesh file in med format
\n resuMeshName = name of the result mesh
\n aboveGroup = name of the group of volumes above the cut plane
\n belowGroups = name of the group of volumes below the cut plane
\n nx ny nz = vector normal to the cut plane
\n px py pz = a point of the cut plane
\n T = 0 < T < 1 : vertices of a tetrahedron are considered as belonging to
\n the cut plane if their distance from the plane is inferior to L*T,
\n where L is the mean edge size of the tetrahedron
\anchor meshcut_plugin
Using MeshCut inside SALOME
When the MeshCut plugin is installed, it can be found in the Mesh menu, sub-menu SMESH_plugins.
\n If the plugin is not installed, the file meshcut_plugin.py is in
SMESH installation in subdirectory bin/salome/meshcut_plugin.py.
\n If there are already plugins defined in a smesh_plugins.py file,
this file should be added at the end.
if not, copied as ${HOME}/Plugins/smesh_plugins.py or ${APPLI}/Plugins/smesh_plugins.py
or in ${PLUGINPATH} Directory.
From the Mesh menu, sub-menu SMESH_plugins, choose "MeshCut" item
The following dialog box will appear:
